In general, the interior itself is good. You can do more realistically by adding a little reflection to the floor (even if it's very dull, there will still be reflexes from walls, objects, only more blurry). Another scale of waves in the basin is better to increase (now they are too small, in comparison with other objects). The camera angle also has considerable significance in perception. In the first form it looks a bit unnatural because the camera's viewpoint is much higher or lower than the usual human growth and the fragment of the ceiling is too small to be seen or to be shown or completely cut. The walls and columns are slightly deviated from the vertical, as if by accident - you need to align the vertical perfectly, or make the view angle even more visible, so that it was perceived that it was intended;) Success!
